The detention basin channel has a capacity of 10.3 ac-ft at the top of the channel embankment. The proposed channel is designed to take run-off from the fully developed upstream basin that contains Southfork Estates Phase 1 through the extended storm drain system.NRCS analysis of fully developed conditions of the site determined the following results for the indicated storm events: Channel A i yr 10 yr 1000 yr Peak Inflow: 247.4 818.3 1821.8 cfs Peak Outflow: 182.0 670.6 1535.1. cfs inflow Vol: 46.8139 .8 266.5 ac-ft Discharge Von 44.0 131.5 259.0 ac-ft Peak Storage: 0.10.8 6.4 ac-ft Peak Elev: 790.9 792.7 795.5 f1.

General Maintenance Procedures The structural and functional integrity of the Facility shall be maintained at all times by removing and preventing drainage interference, obstructions, blockages, or other adverse effects into, through, or out of the system. Periodic silt removal shall occur when standing water conditions occur or the pond's storage volume is reduced by more than 10%.

In addition, corrective measures are required any time a basin does not drain completely within 72 hours of cessation of inflow. NO STANDING WATER IS ALLOWED in basins designed for dry detention purposes. Accumulated litter, sediment, and debris shall be removed every 6 months or as necessary to maintain proper operation of the basin. Disposal shall be in accordance with federal, state and local regulations. Detention facilities shall be mowed monthly between the months of April and October or anytime vegetation exceeds 12-inches in height. To prevent debris from entering and clogging the downstream storm sewer system a wire mesh screen or similar screening device shall be installed over the outlet until final acceptance. 4. PREVENTIVE MAINTENANCE/INSPECTION • Visual inspections of all components will be conducted every 6 months. • A log shall be kept of maintenance actions, and inspections.
